Question

consider the diagram.
lines ac and rs can best be described as
intersecting.
parallel.
perpendicular.
skew.

Explanation:

Step1: Recall line relationships

Intersecting: share a common point. Parallel: coplanar, never meet. Perpendicular: intersect at 90°. Skew: non - coplanar, never meet.

Step2: Analyze lines AC and RS

Line AC is in plane X (vertical plane), line RS is in plane Y (horizontal plane). They are non - coplanar. They don't intersect (no common point) and aren't parallel (not coplanar). So they are skew.

Answer:

skew
